Global Warming: As Seen From Space

Global Warming: As Seen From Space

The glacier known as Jakobshavn Isbrae holds the record as Greenland's fastest-moving glacier. But, starting in late 2000, following a period of slowing down in the mid-1990s, the glacier significantly accelerated in speed and nearly doubled its discharge of ice. This is important for many reasons -- as more ice moves from glaciers on land into the ocean, it raises sea levels. This image from the NASA Landsat satellite shows the movement of Jakobshavn from 2001 to 2003. (NASA/Goddard Space Flight Center Scientific Visualization Studio)
